This invention relates to a combinedclothes washer' and centrifugaldrier involving the use of juxtaposed upright containers mounted upon asingle supporting frame and containing the washing and drying mechanismsrespectively adapted to be driven from the same source of power which ismounted upon the frame preferably in a plane directly beneath thecontainers. f

The main object is to provide a compact washer and drier of the type asa unitary article of manufacture vin which both of the mechanisms may beoperated simultaneously or separately from the same source of power sothat one batch of clothes may be operated upon by. the washing mechanismwhile a previously washed batch may be operated upon by the centrifugaldrier thereby greatly increasing the output without extra work andpermitting the clothes to be more convenient- `ly and directlytransferred from one mechanism to the other without material loss oftime or labor.

Another object is to reduce to a minimum the vibration of the machineincidental to the operation of the centrifugal drier particularly whenrotated at the necessary high speed.

Another object isvto provide means whereby the washing Huid may betransferred from i either container to the as may be required washingand dryits drying element.

Other objects and uses relating to specific parts of the device will bebrought out in the following description.

vAs illustrated, this machine comprises a main supporting frame of thetripod type having a substantiallyhorizontal platform 1 carried by aplurality of, in this instance, three legs 2 which are arranged at theangles of an isosceles triangle and in addition to being secured to theplatform 1 by bolts 3 are also connected to each other some distancebelow the platform by braces 4 and 4 extending along the sides of thetriangle and having their ends secured to the legs by bolts 5.

The lower ends of the legs are provided with castors 2 adapted to restupon the ioor to permit the machine as a whole to be sof moved fromplace to place along the floor as may be more convenient for theoperator as, for example, when using the machinesl in connection withstationary laundry trays in a manner hereinafter described.

The platform 1 is of sufficient horizontal area within its marginal edgeto receive and support a relatively large circular washing vat or tub 6and a relatively small circularv drier vat or tub 7 side by side infixed relation to each other with the larger vat nearest the base of thetriangle and the smaller vat nearer the apex of-the triangle and theaxesv of both vats in a vertical plane lbi-secting the angle at the apexof the triangle and thereb passing through the base of the triangle miway between the adjacent angles.

The vertical axes of the vats wholly within the triangle at the base ofthe triangle 6 and 7 are so that the angles will lie in vertical planessubstantially co-incident with the ad-v jacent sides ofthe vat 6 and atequal distances'from the axis thereof while the angle at the apex of thetriangle willbe in a vertical plane substantially coincident with thecorresponding side of the periphery of the vat 7 and therefore the legs2 which are s e-S cured to the angles of the triangular bracing framemay be substantially straight verticall and secured to the adjacentvportions of tlie peri heries of the vats 6 and 7 and also to the ajacent portions of the perimeter of the platform 1 which follows closelythe circularoutlines of both vats.

The object of this triangular supporting and bracing means for thecombined washer and drier isl to bring all of the mechanism to bebrought into a unitary structure supported on the iloorat three bearingpoints for stabilizing purposes .and also to reduce to a minimum anyvibration incidental to the joint or independent operation of both thewashing and drying mechanism or either of said mechanisms separately aswill be hereinafter more fully explained, it being understood that theplatform 1 serves as a rigid tie connection between the two vats 6 and 7to hold them against relative movement and in differentiating the dryingmechanism from the washing mechanism. it will be observed that thedistinction is only nominal, thewashing mechanism being .employed toloosen the dirt and other foreign matter from the clothes by alternateressure and suction while the .centrifugal drying mechanism serves thedouble purpose of freeing the dirt -K and other foreign matter 1nsolution from the clothes and also for drying the clothes, so thatthellattermay reasonably be termed a supplemental washer as well as adrier.

Washing 'nwchm'sm In additionto the anism comprises a vat 6 the washingmechlurality of, in this instance, two inverte -cup shaped. dashers ormounte cups 8 operatively connected to a yoke 9 which in turn isadjustably mounted on a vertically mounted plunger 10, the latte-r beingreciprocally movable in a suitable gland 11 Iin the bottom ofthe vat 6coaxial therewith while the cups 8 are mounted upon the yoke 9 at oneside of said axis for engagement with the clothes and washing fluid inthe vat as the plunger and cups are reciprocated vertically.- i

Any suitable means may be employed for imparting vertical reciprocatorymotion and also rotary motion to the upright shaft or plunger 10, saidmeans being partially shown in the drawings as consisting of an electricmotor 12 secured to the underside of the plat-- form 1 and having itsarmature shaft 13 connected by a universal joint 14 to a coaxial shaft15 which is journaled in a suitable gear case 16 on the underside of theplatform 1, said shafts 13 and 15 being located at one side of the axisof the vat 6 and parallel with a direct line between the axes of both ofthe vats 6 and 7.

A inion 17 is secured to the driving shaft 15 within the gear case 16and meshes with a gear 18 which is secured to the hub ofa second cpinion19, the latter being loosely upon a counter shaft 20 so as to permit thegear and pinion to rotate relatively 'to said shaft for a purposepresently ldescribed.

The pinion 19 meshes with a relatively large gear 21 which is looselymounted upon a crankshaft 22 for relative rotary movement and also hasan independent axial movement into and out of clutching engagement witha clutch member 23 having an elongated hub journaled in a bearing .24 inthe adjacent end of the gear case 16 and carrying at its outer end acrank arm 25,.

The hub of the clutch member 23 together with the cra-nk arm 25 arekeyed to eachother and to the shaft 22 by means of a key or pin 26,Figure 6, to cause those parts to rotate mvumson.

The crank arm 25 is operatively connected in any well known manner tothe intermediate portion of a rock arm or lever 27 extending radially toand at one side of the axis of the vat 6 below the platform 1 and havingone end pivotally connected at 28 to the outer lill exge of the platformand its inner end snita y connected to the lower end of the plunger 10whereby as the shaft 22 with the crank arm25 thereon is rotated throughthe medium of the gear -train and clutch previously de'-l scrihedrocking motion will be imparted to the rock arm or lever 27 forreciprocating the Y pluger 10 and thereby effecting a correspondingreciprocatory movement of the yoke 9 and cups 8 carried thereb A coiledspring 29 may well known manner to the lever 27 and to the frame of themachine for retracting the inner be connected in any mitting axialmotion to the clutch gaging said gear clutch with the end of the leverand upwardly and thereby lifting those parts. v

The counter shaft 2O is located between the axes of the vats 6 and `7and approximately in a direct line between said axes while the drivingshaft and crank shaft 22 are located at opposite sides ofand parallelwith the counter shaft and therefore at opposite sides of the verticalaxis of the vat 6 and plunger 10 while the motor 12 and gear case 16containing the gear train connections between the drivingshaft 15 andlever 27 are also located at opposite sides of the lever 27 and plunger10 so that the load incidental to the operation of the cups 8 forwashing purposes is nearly in the center of the power pla-nt 011 theunderside of the platform 1 for the purpose of distributing the powertransmitting mechanism more evenly aro-und the plunger and therebyintroducing a more effective balance andv consequent reduction ofvibration in the operation of the washing mechanism.

As previously stated the clutch gear 21 is movable axially into and outof clutching engagement with the clutch member 2.3 and for this purposeis provided with apertures -30 adapted to receive studs -31 on themember 23 when the two parts are brought together for transmittingmotion from the pinion 19 to the crank shaft 22.

The hub .of the clutch gear 21 is provided with an annular groove 32 forreceiving a shifting member 33 which is connected to one end of ashifting rod 34, Figure 67 said split rod being mounted in a suitablebearing in the adjacent side of the gear case 16l and having its outerend connected to o ne end of a shifting lever 35.

This lever 35 is pivoted at 36 to the gear case 16 and has its other endconnected by a link 37 to a crank arm 38 on the lower end of an uprighttubular shaft 39, Figure 2.

The tubular upright shaft 39y extends upwardly along the outside of.andin close proximity to the vat 7 and has its lower end journaled in asuitable gearing 40 on the platform 1 and itsfalpper end provided with ahand lever 41 secured thereto for rocking said shaft about its axis andthereby transgeai 21 through the medium of the link 37, lever 35 andshifting rod 34 for engaging and disenclutch memparts carried therebyassisting the motor in It is now evident that while the motor 12 is inoperation positive motion will be transmitted to the gear clutch 21 andthat if the hand lever 4l is shifted in one direction the clutch gear 21will be forced into engagement for operating the crank sha-ft 22 andthereby reciprocating the plunger 10 with the cups 8 thereon forwash-ing purposes while on the other hand if the hand lever 41 isshifted in i @entri/@Loyal drier An upright cylindrical cage 42 isrotatably mounted within the vat 7 coaxial therewith but clear from thewalls thereof to avoid friction therewith and comprises a perforatedbell 43 having its lower end secured to a circular supporting plate orbottom 44 and its upper end provided with a concave-convex cap or lid 45removably mounted thereon but frictionally engaged therewith to berotated thereby in a manner hereinafter described.

T he counter sha ft 20 is connected by auniversal joint 46 to an axialextension shaft 20 which is journaled in one side of a gear case 47 andis operatively connected by a beveled gear 48 and pinion 4Sto an uprightshaft 50 which is journaled in a suitable gland 51 in the platform lcoaxial with the axis of the cage 42 and has its opposite end providedwith a hexagonal or other angular head 52 engaging in a similarly formedangular recess 53 in the bottom plate 44 for transmitting rotary motionfrom said upright shaft 50 to the cage 42 and permitting said cage to beremoved from the head 52 by upward displacement when desired.

The gear case 47 is secured to the underside of the platform 1 as shownin Figure 4 andis provided in its lower side with an adjustable endthrust bearing screw 54 for the lower end of the upright shaft 50 andthereby to hold the rotary head 52 out of frictional engagement with theupper end of the gland 51 which is preferably of the stufing box type toprevent leakage of water from the bottom of the vat 7 through the gland.

Suitable means is provided for controlling the operation of thecentrifugal drier mechanism independently of the washing mechanism whilethe motor is in operation and as previously stated the gear 18 which isdriven continuously by the motor through the medium of the pinion 17 isloosely mounted upon the shaft 2O to rotate independently thereof and isprovided with a conical clutch face adapted to be engaged by a conicalclutch member 56 on one end of a brake drum 57 which is splined on theshaft 2O for axial movement and is spring-pressed in one direction by acoiled spring 58 for frictionally engaging the vclutch member 56 withthe clutch gear 18 for transmitting motion to said shaft 20 and thencethrough the shaft 20 and gears 48 and 48 to the upright shaft 50 forrotating the cage 42, the clutchmember 56 being riveted or otherwisesecured to the hub of the brake drum 57 as shown in Figure 4. i

The brake drum 57 is provided with an `outwardly projecting annularflange having a friction washer 57 of fibre or equivalent materialadapted to be engaged by a brake shoe 59l constituting a part of theclutch shifting means.

An upright rock shaft is journaled in suitable bearings in the gear case16, Figure 6, and has its lower end provided with a crank arm 61pivotally connected at 62 to the brake ring 59 and its upper endprovided with a crank arm 63 connected by a'link 64 to a crank arm onthe lower end of an upright rock shaft G6 which extends verticallylthrough the tubular shaft 39 coaxial therewith and has its upper endjournaled in the adjacent side of frame 67 and is provided with a handlever 68 by which it may be turned for shifting the clutch member 56into and out of clutching engagement with the clutch gear 18 and alsoyfor moving the brake ring 59 into andout of engagement with thefriction face 57 of the brake drum 57.

The frame 67 embraces a portion of the periphery of the upper end of thewashing vat 6 and may be rigidly secured thereto by brazing or othersuitable lfastening means and extends entirely around the upper end ofthe drier vat 7 to which it may be also rigidly secured by brazing orotherwise to form a rigid tie between the upper ends of both vatsforvholding them in fixed relation, said frame being provided with acentral cylindrical opening 69 of' sufficiently large diameter to permitthe Acage .42 to be withdrawn therethrough by upward displacement whendesired er Areplaced' by downward displacement into interlockingengagement -with the driving head 52.

A'lid or cover 70 for the opening 69 is hinged at one side at 71 to theframe 67 at a point beyond the adjacent side of the vat 7 and whenclosed is adapted to engage the upper inner faces of the walls of theopening 69 to form a substantially water-tight joint therewith or it isheld in place by a locking bolt 72 and spring 73, both guided in abushingv 74 in the adjacent side f the frame 67, the outer end of thebolt being provided with 9.a handle 75 by which it may be Withdrawn fromits locking position against the action of its retracting spring 73,Figure 3.

The lid is also concave-convex in cross sectionv and is provided at theside nearest which it may be opened and closed.

The lever 68 which controls the operation of the centrifugal drier cage42 is provided with an extension 68 movable into and out o f engagementwith theupper facev of the adjacent side of the lid 70 for locking saidlid in its closed position when the lever 68 is adjusted to cause therotation of the cage 42 and to release said ld when the lever is G5adjusted to stop the operation of the cage,

but the lid 70 cannot be raised until it is further unlocked bythewithdrawal ofthe j bolt 72 thereby reducing the liability ofopenrotation of the cage it will be necessary to withdraw the bolt 72 torelease the lid 70 and permit it to be opened.

The cap 45 covering the upper open end of the cage 42 is centrallyjournaled by antifriction bearings 7 6 upon a suitable supporting stud77 on the underside of the lid 70 so that when frictionally engaged withthe upper end of the cage-it will rotate freely therewith and will alsoserve to hold the cage against excessive vibration in case the clothestherein should be slightly heavier on one side than on the other whilethe cage is being rotated at high speed.

The upright perforated walls of the cage 42 are arranged in sufficientlyspaced relation te the inclosing walls of the vat 7 to permit thewashing or rinsing fluid to be thrown by centrifugal force from theclothes through the perforated side walls of the cage and into thesurrounding portions of the vat as the cage is rotated, the gear ratioof the driving mechanism for the cage being such as to rotate said cageat a sufficiently high s eed to expel practically all of the moisturerom the clothes by centrifugal force so thatafter a comparatively briefperiod of operation the clothes are practically dry and more or lessfluffy ready for smoothing by a suitableY ironing mechanism.

Suitable means is also provided for assistcircumferential series ofvanes or ribs 8() extending outwardly from the center thereof andpreferably onthe upper face of the cover 45 and arranged so as to createcirculation of air from the top downwardly through the openings 78 and79 and thence through the clothes in the revolving cage and out throughthe perforations in the side walls of said cage into the outer containerfrom which it is drawn into and through the pump, it being understoodthat during such rotation the clothes arethrown with considerable forcefrom perforated walls of the cage leaving more or less air space in andaround the axis of the cage and permitting circulation of air therethrouh leaving. the yclothes in a substantially ry fluffy condition. Y

It will be observed upon reference to Fi ure 4 that the brake shoe 59operates direct y against the brake surface 57 of thebrake drum 57 ytodisengage the clutch member 56 1 the center and against the from theclutch gear 18 against the action of the retracting spring 58 whichserves to retract both the clutch member 56 and brake drum 57 underwhich conditions the application of the brake simultaneously with thewithdrawal of the clutch member 56 will retard and stop the rotation ofthe shafts 2O and 20 and cage 42 driven thereby, all of which greatlyexpedites the centrifugal drying operation and enables both the brakeand clutch to be controlled by the same lever 68 which is coaxial withand in proximity to the Washer controlling lever 41` as shown in Figure2 thus permitting both levers to be operated from the same side of themachine.

This proximate coaxial operation of the two levers 41 and 68 alsopermits the use of coaxial detents 81 and an interposed coiled spring 82arranged with a socket in the adjacent portion of the frame 67 forengaging in recesses in the adjacent faces ofthe levers 41 and 68 tofrictionally hold them in their different positions of adjustment` theshaft 66 and lever 68 carried thereby having slightly vertical movementagainst the action of a retracting spring 83 between the hubs of thecrank arms 38 and 65 to adjust the engagement of the. extension 68 withthe upper face of the lid when the latter is closed and also to assistin frictionally holding the shaft 66'and tubular shaft 39 againstaccidental displacement from their adjusted positions.

i Fluid circulating mechanism Suitable means is provided for withdrawingthe washing or rinsing fluid 'from both of the vats 6 and 7 and also fortransferring the suds or other fluid from the drier vat to the washingvat and for these purposes the bottom of the Washing vat 6 is providedwith an outlet nipple 84 to which is connected one end of a valve case85 having its other end connected by a conduit 86 to the inlet side 87of a rotary pump 88, the latter having its impeller 88 upon the drivenshaft 15, the pump casing forming, in this instance, a part of the gearcase A16 as shown more clearly in Figures 6 and 8.

The conduit 86 is connected by a branch 89 to an opening 90 in thebottom of the drier vat 7 to form a liquid tight joint therewith therebyestablishing open communication between the interior of the drier vat 7and inlet 87 of the pump 88, see Figures 6 and 13.

The inlet opening of the valve case 85 is controlled by a valve 91 whichis yieldingly mounted upon a crank arm 92 of a rock shaft 93, the latterbeing journaled in one side of the valve case 85 and provided with anexternal hand lever 94 by which the valve may be opened and closed atwill as maybe remounted directly v quired to retain or to discharge thewater in and from the vat 6.

The outlet side of the pump 8 is connected by a. conduit 95 and'nipple95 to a valve chamber 96 in the frame 67, said valve chamber havingbranch openings 97 and 97. leadfrom opposite sides thereof andcontrolled by a hollow valve 98 having -an external operating member 98and a radial opening 99 which may be brought into registration with oneor the otherof the branch passages 97 or 97 to vary the direction foflow of water from the valve chamber.

The branch passage 97 is connected by an elbow 100 to an inlet openingin one side of the washing vat 6 near the upper end thereof While thebranch passage 97 is connected to a discharge nozzle 101 adapted todischarge over a water table 102 intoV a stationary laundry tray A orother receptacle.

.In Figures 6 and l1 the valve 98 is adjusted to divert the water fromthe pump into the -nozzle 101 but by turning it onehalf turn the opening99 may be registered with the branch 97 to divert the water from thepump back into the washing vat 6.

The drain board 102 extends under the adjacent end of the frame 67 atthe side of the vat 7 opposite the vat 6 and is preferably hinged at 104to said frame andv provided with opposite concentric slots 105 forreceiving clamping bolts106, Figure `1, by which the drain board may betilted to different angles to or from a horizontal plane and locked inany position of adjustment as may be required to direct the waterdischarged from the nozzle 101 into a suitable receptacle as the vat A.

Operation The clothes to be washed together with a suitable washing Huidforming what may be termed suds, is placed in the vat 6 beneath the cups8 under which conditions the valve 91 will, of course, be closedIl toretain the washing iuid in the vat. Y

The electric motor 12 is then started by the operation of any suitablecontrolling switch thereby operating the pump 88, gear 18, its pinion 19and gear 21. l

Throwing the clutch Agear 21 into engagement with the clutch member 23will cause the operation of the lever 27 and plunger 10 carrying thecups 8 for washing the clothesA in the vat by alternate pressure andsuction as the cups are reciprocated vertically into and out ofengagement with the clothes.

As soon as the clothes are properly washed in the vat 6 they may bewithdrawn therev from by hand across the frame67 and into the cage 42which has been previously opened los for such purpose by opening thelid`70 carly washed clothes are placed Within the revoluble cage 42substantially filling the same, the lid 70 with the cover plate 45thereon is closed and locked in its closed positionwith the cover plate45 frictionally engaged with the upper edge of the cage 42 to rotatetherewith, it being understood that the lid 70 will then be firmly heldagainst rotary movement.

The lever 68 and its rock shaft 66 are then turned in the properdirection for releasing the brake shoe 59 and simultaneously engagingthe clutch 56 with tlieclutch gear 18 for transmitting rotary motionfrom said gear to the shaft 20 and thence through the shaft 20 andupward shaft 50 to the cage 42 which with the wet clothes therein isdriven at relatively high speed to expel practically all of the moisturefrom the clothes through the perforated walls of the cage and into thevat 7. y

As previously stated the lower end of the Vat is in open communicationwith the inlet side of the pump 88 through the pipe 89 and owing to thecontinued operation -of the caf j receptacle" or waste out through thepassage 97 and pump 88 the washing fluid accumulating in the vat 7 willbe withdrawn therefrom and forced through the pipe 95 into theI valvechamber 96 and by adjusting the valve 98 to the position shown inFigures 6 and 11 the washing Huid withdrawn from the vat 7 will beforced outwardly through the passage 97 and nozzle 101 Vinto one or theother of the laundry trays A or into any other suitable pipe.

Or, if it is desired to withdraw the washing fluid from the vat 6 it maybe accomplished by simpl opening the valve 91 and allowing the lui inthe vat to pass through the conduit 86 into the inlet side of the pump88 from which it will be expelled through the pipe 95 into the valvechamber and thence nozzle 101.

On the other hand, assuming that it is desired to return the suds wateraccumulating in the vat 7 and that the valve 91 is closed, the valve 98may be reversed to cut off communicationl between the conduit 95 andbranch 97 and to open communication between said conduit and the branch97 thus rniitting the water to be thrown directly om the -drying vat 7and'discharged into the upper portion of the washing vat 6 thuspermitting the re-use of the same suds as long as may e desired withoutvarying the amount of water in the washing vat and at vthe same timemaintaining a continuous withdrawal of the uid from the clothes in the ding vat.-

t will be evident from the foregoing descri tion that as soon as thepreviously was ed clothes have been transferred from the. washing vat 6to the drier cage 42 and durin the lcentrifu al drying operation anadditional batch o soiled c othes may be placed iii the .washing vat andoperated upon by the washing mechanism without disturbing the operationof the drier cage, all of which greatly increases the output of themachinel and insures a complete washing and drying" of the clothes withthe expenditure of a minimum amount of labor and expense and withoutliability of injuring the finest of fabrics or mutilation of any partsthereof and at the same time permitting either mechanism to be operatedindependently of the other or simultaneously as may be required.
